Stop trying to touch files untracked by Blizzard

I like using Git to backup and version control various things in my life.
My WoW addons and WTF folder are one of those things.
And everytime I make a new backup I get to wait 1-10minutes to see BNet Application “Initializing…” and “update” while the application keeps failing to change permission on my .git folder and files.

fix_permissions path="J:/GAMES/World of Warcraft/_classic_/.git/objects/00/024dbd488b8935cefc9f3df268d2b5e9d09c2e" failed to remove read only flag from file attributes
